Extending upward from the beams 4 and 5 are standards or corner-posts 8,which are connected by upper longitudinal bars 9 and also by means ofpivoted yokes 10, the yokes being pivotally connected at 11 to thestandards at one side of the machine and adapted to brace the otherstandards, as shown in Fig. 6, each yoke being provided with a set-screw12, by means of which the distance between the upper ends of thestandards may be accurately adjusted, the said set-screws passingthrough the end portions of the yokes and bearing against the standardsembraced thereby. The upper longitudinal side bars 9 form 4the supportsand guides for a pair of wedgeshaped jaws or saw-blade clamps 13, whichare adapted to slide'lengthwise of the machine and he reciprocated backand forth by means hereinafter particularly described. rlhe side bars 9and jaws 13 have a dovetailed engagement with each other, each of thejaws 13 being by preference provided with a dovetailed rib or projection14, which is received in a corresponding recess 15 in the contiguoussurface of the side bar. The arrangement of ribs and recesses may,however, be reversed b y placing the dovetailed ribs on the side barsand recessing or grooving the jaws 13 to receive the same. l

The jaws or clamps 13 are adapted to clamp the saw-blade 16 betweenthem, as best illustrated. in Figs. 1, 4, and 6, the saw-blade beingautomatically clamped and released by a simultaneous movement of theclamps lengthwise of the machine. In order to simultaneously and equallymove the wedge-shaped sliding clamps 13, I connect each clamp with thestationary machine-frame by means of a` pair or set of toggle-arms 17and 18, the arms 17 being terminally and pivotally connected to the rearend portions of the jaws 13 at the point 19, while the arms 18 areterminally and pivotally connected to the machine-frame at 20. Themeeting ends of the toggle-arms 17 and 18 are pivotally connected witheach other and with one end of the link 21, which connects pivotally atits lower end to the extremity of a lever-arm 22, connected with a sawclamping and feeding lever 23, fulcrumed in a bearing-block 22, mountedupon one of the longitudinal bars 1 and provided with a suitableoperating-handle 24. The lever 23 extends upward at one side of themachine, so as to be conveniently operated by an attendant. VIt will beunderstood that two sets of toggle-arms 17 and 18 and links 21 areemployed, one set at each side of the machine, both links beingconnected with the lever-arm 22. Therefore both clamping-jaws 13 aresimultaneously and equally advanced and retracted for clamping andreleasing the sawblade.

26 designates the swaging-head, which is carried by the jaws 13. Thehead 26 is pivotally mounted at 27 in the projecting ends of a pair ofswinging supports 28, which extend backward a suitable distance and havetheir rear end portions 29 received in shallow recesses 30 in the outersurfaces of the jaws 13, as shown in Fig. 6, said supports beingnotched, as shown at 31, to engage pins 32, arranged in the recesses 30.rlhe hooked and notched rear end portions 29 of the supports 28 are thuspivotally connected with the jaws 13, so as to allow the pivoted ends ofsaid supports carrying the swaging-head to rise and fall. ln this way asthe sliding jaws are moved outward to release the saw the swaging-diecarried by the swaging-head can be moved to ride over the teeth of thesaw and successively engage the same and be brought automatically intoproper swaging position. When the jaws reach the limit of their outwardmovement, the

swaging-head will assume a position with thi-F swaging-pin in the recessbetween two of the teeth, and when the jaws are closed to clamp the sawtheir forward movement will carry the head forward, which through itsengagement with the teeth of the saw will pull the saw forward to beoperated upon, the operation of the swage in feeding the saw beingclearly illustrated in Fig. 2 of the drawings. Disengagement between thesupports 28 and the jaws 13 is prevented by means of a pair of keepers33, arranged in recesses in the jaws beyond the end portions 29 of thesupports 28, each of said keepers 33 being pivotally mounted at 34,provided with a shoulder 35 to engage the adjacent support 28, and alsohaving an operating handle or projection 36.

The swinging supports 28 are provided with arc-shaped extensions 37,having slots 38 to receive screws or fasteners 39, which pass throughthe slots 38 into the upwardly-extending portion of the swaging-head 26,thereby providing for relative adjustment between the sWaging-head 26and the supports 28 in order to vary-the angle of presentation of theswaging-die and anvil hereinafter described. The swaging-head issubstantially L-shaped and is provided with a central recess for thereception of the anvil 40. This anvil is supported at the rear by meansof an adjustingscrew 41, at the top by means of another adjusting-screw42, and at the side by means of a third adjusting-screw 43. By means ofthe screws 41, 42, and 43 the anvil may be adjusted forward andbackward, up or down, and laterally in either direction until it hasbeen brought to the proper swaging position for the teeth to be operatedupon. rlhe swaging-die is in the form of a pin 44, which passeshorizontally through the swaging-head from side to side and has itsextremities connected with the branches 45 of the bifurcated shank 46 ofa swaging handle or lever 47. By bifurcating the shank of theswaging-lever Vthe strain is equally divided upon the opposite lOO IOS

ends of the swaging-pin 44. The central portion of the pin, or thatportion which acts as a die, is slightly flattened or recessed, as shownat 48, and as the lever 47 is turned such flattened or recessed portionof the die is brought into contact with the lower side of the tooth,compressing and expanding the tooth against the anvil 4() and effectingthe proper swaging thereof.

Connected with the forward projecting portion of the swaging-head is abracket 49, having a recurved and apertured end portion 50 for thereception of the discharge nozzle or spout of an oil-cup 51. Immediatelybeneath the discharge end of the cup 51 is arranged a brush or spreader52, which moves in contact with the saw-teeth as the sliding jaws 13 arereciprocated, thus spreading the oil or other lubricant upon the teeth.The bracket 49 is provided with slots 49, which receive suitablefasteners connected with the swaging-head, thus providingfor thenecessary" adjustment of the lubricating device to position thespreading-brush properly with relation to the saw-teeth.

53 and 54 represent saw guides or rests arranged at or near the oppositeends of the machine, one of the guides, as 54, being in the form of aslotted and 'vertically-adjustable plate, by means of which thesaw-blade may be adjusted vertically to bring the teeth into properrelation to the swaging-die and anvil. The saw blade is also supportedupon a grooved roller 55, which is journaled in a sawrest frame 56,pivotally connected at one end at 57 to the machine-frame and providedat its opposite end with an abutment or shoulder 58, which rests uponthe upper extremity of the adjusting-screw 59, provided with ahand-wheeler head 60. By turning said screw the saw-blade may be raisedor lowered with accuracy until the swaging-die and anvil are broughtinto proper relation to the saw-teeth, after which the rest 54 may beadjusted to form a permanent gage for the saw-blade.

rlhe limit of the movement of the swaginglever 46 may be fixed by meansof a stop 6l, adjustably mounted at 62 on the top of the swaging-head26.

63 represents bolts extending transversely of the frame and connectingthe beams 4 and 5to prevent the same from spreading under the action ofthe saw-clamps. These bolts also assist in the lateral adjusting andsecuring of the beam 5.

Each of the sliding clamps 13 is provided at a suitable point andpreferably nearthe wider end with a holder 64, in which is received aside-dresser 65 in the form of a steel pin. rlhe side-dressers 65 arearranged exactly opposite each other, and as the wedgeshaped jaws closetogether upon the saw-blade said side-dressers operate by compressionupon the teeth and serve to properly aline the same.

From the foregoing description it will be Aunderstood that by operatingthe saw clampwith the next or the desired s aw-tooth. Then as the leveris thrown back or moved in the opposite direction the swaging-pinengages the saw-tooth, directing the saw-blade along with the jaws. Asthe jaws approach the inward or rearward limit of their movement theyfirmly grasp and clasp the saw-blade between them, thus firmly holdingthe blade while the operator manipulates the swaging handle or lever 47.Thus a single lever operates to simultaneously advance or retract thejaws and the swaging-head and to feed the saw-blade through the machinewith au intermittent movement.

A machine constructed in accordance with the present invention providesa solid foundation and means for firmly clamping the saw while beingswaged, while by providing the double or bifurcated swaging-levertwisting of the teeth while being swaged is avoided. A singleoperating-lever serves to position the saw, clamp the same, and also tosidedress and oil the teeth. The saw-clamping jaws may be made of anysuitable length and width to provide the necessary frictional hold andgrasp upon the saw. By using clamps of the class described there is nodanger of cutting into the saw-teeth, thereby leaving the saw smooth andenabling the filers to obtain an even smooth edge on the tooth. Noadjustment is required for saws of various gages within certain limitsand the swaginghead is adjustable for teeth of different angles. Anotherimportant feature resulting from a construction set forth resides in thefact that by lifting the keepers and disconnecting the swaging-head andits supportingarms from the sliding jaws the saw-blade may be put intothe frame between the jaws and from the top. The saw-blade may beremoved in the same way.

l do not desire to be limited to the details of construction andarrangement hereinabove set forth, and accordingly reserve the right tochange, modify, or vary the construction within the scope of theappended claims.

Having thus described the invention, what is claimed as new isl. Asaw-swaging machine having a frame, sliding clamping-jaws, meansrendered effective by the sliding movement for opening and closing thejaws, and a swaging-head carried by the jaws, said head constructed andarranged to cooperate with the jaws to advance the saw during theoperation of closing the jaws.
